Asymptotical quasinormal mode spectrum for piecewise approximate effective potential
Wei-Liang Qian, Kai Lin, Cai-Ying Shao +2
It was pointed out that the black hole quasinormal modes resulting from a piecewise approximate potential are drastically distinct from those pertaining to the original black hole…
Cosmic evolution of dark energy in a generalized Rastall gravity
Kai Lin, Wei-Liang Qian
In this work, we propose a scheme for cosmic evolution in a generalized Rastall gravity. In our approach, the role of dark energy is taken by the non-conserved sector of the stress…
On quasinormal frequencies of black hole perturbations with an external source
Wei-Liang Qian, Kai Lin, Jian-Pin Wu +2
In the study of perturbations around black hole configurations, whether an external source can influence the perturbation behavior is an interesting topic to investigate. When the…
Dirac quasinormal modes of power-Maxwell charged black holes in Rastall gravity
Cai-Ying Shao, Yu Hu, Yu-Jie Tan Cheng-Gang Shao +2
In this paper, we study the quasinormal modes of the massless Dirac field for charged black holes in Rastall gravity. The spherically symmetric black hole solutions in question are…
Spherically symmetric static black holes in Einstein-aether theory
Chao Zhang, Xiang Zhao, Kai Lin +3
In this paper, we systematically study spherically symmetric static spacetimes in the framework of Einstein-aether theory, and pay particular attention to the existence of black ho…
No static regular black holes in Einstein-complex-scalar-Gauss-Bonnet gravity
Kai Lin, Shaojun Zhang, Chao Zhang +3
In this brief report, we investigate the existence of 4-dimensional static spherically symmetric black holes (BHs) in the Einstein-complex-scalar-Gauss-Bonnet (EcsGB) gravity with…
